This may be the article I’ve hesitated longest over publishing. Its subject matter has always hovered as a specter over my writings on the close relation between human capital and economic growth; an obvious but studiously ignored presence*. I am talking, of course, about race and IQ. Of racial differences in IQ, to be precise.

Why now? First, it’s a propitious moment to raise the issue, what with the recent publicity surrounding the Trayvon Martin case and the firing of John Derbyshire from The National Review (for writing an article in another magazine whose recommendations most liberals follow in private even as they denounce it as incorrigibly racist in public). But my purpose isn’t to get attention as such. On these matters, it tends to come from unwelcome quarters, either from the PC police (who regard any discussion of race other than to deny it as crimethink), or from the reactionary White nationalist crowd, who think they’ve stumbled on ideological soul-brethren (thanks but no thanks, or to quote Robert Lindsay, “We’re never getting a boarding pass. Never!”). I suspect being a liberal race realist is somewhat akin to being a Jew before anti-Semitism went out of fashion. You get fired on from all sides. Not fun.

The second, more substantive reason, is that the issue matters. If it was an irrelevance, I obviously wouldn’t bother (though tellingly, most people have no problem discussing genetic causes for relatively unimportant things, such as the preponderance of Kenyan marathoners, or East Asians’ lack of alcohol tolerance). But there is a mountain of evidence indicating that IQ levels have a very real and direct influence on the world, from the life earnings potential of individuals to the wealth and poverty of nations.

This is a futurist blog, and it has never shied away from inconvenient but pertinent observations that go against Establishment orthodoxy, e.g. that the world is finite, and industrial growth in its current form is unsustainable. As regards its distribution, my views on the sources of prosperity would discomfit both left and right; contrary to theorists from both camps, it is mainly determined by levels of human capital, both within nations and internationally (the two major outlier groups, countries with resource windfalls or central-planning legacies, are exceptions that prove the rule). A corollary is that if there are genetically rooted differences in IQ between races that go beyond the power of racism or exploitation to explain, then there would be variegated ceilings on the extent to which human capital can be developed in different nations and different societies. It would also mean that major inequalities in global development are here to stay.

But first, a much-needed definition of terms to clarify why Race Realism (or “Human Biodiversity”) is not coterminous with Racism.
